Fed is obviously a favor but wouldn't be shocked if Raonic upsets him. Fed struggling with ros big time these days and Milos is one of better tie break players. The match will be decided by point or two. Won't be an easy 3 setter for sure

The key in the previous meetings has been Fed's struggles returning Milos' 2nd serve. I think Fed struggles against Milos more than many other big servers due to Raonic's ability to get serves to kick really high to Fed's backhand, which Fed does not like.
